Abstract

The corrosion resistance characteristics of glass fibre reinforced polymer (GFRP) bars make them a promising substitute for conventional steel in continuously reinforced concrete pavements (CRCP). However, GFRP bars have never been used in a CRCP highway experiencing regular or high traffic. This paper presents the design and construction of first CRCP slabs reinforced with GFRP bars that was implemented on Highway 40 East (Montréal). The demonstration area reinforced with GFRP bars represents a 150 m long section of the highway with the full width. The demonstration area was divided into 18 slabs of 25 m long by 3.7 m wide each. The eighteen slabs were designed and constructed to investigate the different parameters known to affect the performance of such CRCP slabs. Varieties of sensors were installed in this project to monitor the early-age behaviour, repeated load effects, and environmental conditions on the performance of the CRCP slabs. This includes different types of electrical resistance strain gauges and fibre optic sensors (FOS) to measure reinforcement and concrete strains. In addition, thermocouples and FOS have been used for temperature measurements. Design concepts, construction details, properties of used materials, early-age behaviour and preliminary monitoring results of the GFRP-CRCP slabs are presented in this paper.
